Each product must be tested rigorous, and the service life of lithium batteries is also the key to detection. Many manufacturers will conduct a series of tests when they release a new lithium battery. Take test data, assuming that the service life of the battery from 300 to 500 times, if it accurately calculates it to 400 times, the actual battery life will definitely be than 400 (full charge, discharge situation) less. It's much more. Manufacturers can choose the material, design structure and use technology of the battery, but the use environment of the battery, the external environment will change, and the frequency of the user's (mobile phone) device. These factors will produce the service life of the battery's usage life. Influence.

　　Take the lithium battery of the mobile phone, in the previous article, we once said that the theoretical charging of lithium batteries is about 300-500 times. If the user is charged every two days, we need to perform 180 times a year in one year. The left and right charging, but most of the mobile phone batteries have been used for more than three years. Why hasn't it been eliminated?

　　You know, the service life of the battery is limited, but its service life is gradually shortening. It is not eliminated at the beginning, but gradually gradually gradually gradually gradually eliminated. For shortening, many users say that after a period of use, the battery life of the battery will become worse and worse, but most of the time, most mobile phones will have a decline in battery life, but even in the theoretical service life, in fact, in fact, in fact, in fact, in fact, in fact, in fact, in fact, in fact, in fact, in fact, in fact, in fact, in fact, in fact It can still be used, but the proportion of performance decline will be more than 20%.
